Naproxen is synthesized from 2-methoxynaphthalene and the (+)-isomer obtained by resolution with cinchonidine (61). It was introduced in the United States in 1976 and, as a generic drug, has consistently been among the more popular NSAIDs. It is marketed as the S-(+)-enantiomer, but interestingly, the sodium salt of the (-)-isomer also is on the market as Anaprox. As an inhibitor of prostaglandin biosynthesis, it is 12 times more potent than aspirin, 10 times more potent than phenylbutazone, three to four times more potent than ibuprofen, and four times times more potent than fenoprofen, but it is approximately 300 times less potent than indomethacin.
